LESLIE CHARLES LEACH (1909-1996)

Leslie Charles Leach (Figure 1), known to friends as

Larry, was bom at Southend-on-Sea in Essex, England on

18 November 1909. After leaving school he passed the

entrance exam ination o f the British Army Technical

School where he completed a course in electrical technol­

ogy Serving as an Army technician, he gained wide ex­

perience in electrical engineering. He applied successfully

for a post in Southern Rhodesia [now Zimbabwe] and

arrived in Salisbury [now Harare] in January 1938. Here

he met and married Ann (often called Nan) in 1939. In

1944 he established his own business, following the ac­

quisition o f premises on Sinoia Street in Harare. Concern­

ing himself mainly with the supply of electrical equipment

for vehicles and aircraft, he traded productively under the

name of L.C. Leach.

Larry’s interest in succulents started in 1950 after he

had purchased a 10 acre plot near Harare, which he named

‘Farview’. Initially he cultivated a variety of plants, but

gradually his attention centred on succulents. Larry en­

deavoured to learn more about succulents than could be

gleaned from available literature or expertise. Soon he be­

gan to concentrate on the systematic collection of Stape-

lieae, Euphorbieae and species of

Aloe

.

In 1956, after selling his business, he visited the eastern

Transvaal [now Mpumalanga] and southern Mozambique

to compare

Euphorbia confinalis

R.A.Dyer with closely

related plants that he had studied in Zimbabwe. At that

time he purchased a 25 morgen plot south of Nelspruit.

Satisfied that the Zimbabwean plants were distinct from

E. confinalis

, he soon embarked on several, mainly self-

financed expeditions to investigate and collect the species

of the

Flora zambesiaca

area, and to see as many succu­

lent euphorbias as possible at their type localities. After

the death o f his wife in 1958, following a long illness, he

intensified his research efforts. The journeys encompassed

m ost o f southern Africa, including Zam bia, Angola,

Mozambique, South Africa and Namibia, as well as Tan­

zania and Kenya. He was at times accompanied by R.D.A.

Bayliss, I.C. Cannell, H. Hall, A.R.A. Noel, A. Percy-

Lancaster, R.O.B. Rutherford-Smith, E.A.C.L.E. Schelpe,

J.A. Whellan, G. Williamson, and H. Wild. His extensive

expeditions are sum m arized in Codd (1966), Schelpe

(1969) and Gomes e Sousa (1971).

The Angola trip in 1967 was partly financed by grants

from the CSIR. On this occasion he collected several new

records of ferns, written up by Schelpe (1968). These col­

lecting trips were often fraught with difficulties and dan­

g ers. Tw o attem p ts to reach G oa Islan d , northern

Mozambique, to see

E. angularis,

failed because of an

allergy to mosquito bites, which he had developed on a

previous excursion. However, at the third attempt, with

the assistance of the Portuguese Naval Authorities, he

landed on Goa Island only to find that

E. angularis

was

neither flowering nor fruiting. Three years later, he was

back on Goa Island, collecting flowers and fruits. In 1962

Larry was accompanied by Schelpe to collect ferns and

Euphorbia

spp. in northern M ozambique. However, a

near-fatal viral dysentery grounded the expedition for a

week in Blantyre.

From 1972 to 1981, Larry worked as Honorary Bota­

nist on the staff of Zimbabwe’s National Herbarium. Here

he described himself as ‘probably Rhodesia’s only unpaid

civil servant’. Larry persuaded the Aloe, Cactus and Suc­

culent Society of Zimbabwe to publish a taxonomic series

supplem entary to

Excelsa.

Four volum es, containing,

among others, monographs of the Stapelieae taxa

Orbea,

Stapelia

,

Huemia

and

Tridentea,

appeared between 1978

and 1988 with Larry as the sole author. In December 1981

he emigrated to South Africa and settled first at the Bo­

tanical Research Institute in Pretoria (Figure 2) and was

then employed at the National Botanic Garden at Worces­

ter from 1982 to 1989. Until the time of his death he was

employed as Honorary Research Fellow in the Depart­

ment of Botany of the University of the North. Larry

passed away on 18 July 1996 at the age of 86. Sadly he

could not complete the treatment of the succulent Euphor-

biaceae for

Flora zambesiaca

which would have

nated forty years of immensely dedicated research on

Euphorbieae and Stapelieae.

In later years Larry spent ‘far too m uch’ time on no-

menclatural disputes. The identity of the controversial

name,

Euphorbia candelabrum

is such an example (Carter

1982, 1985, 1988; editor’s notes in

The Euphorbia Journal

4: 4 (1987); Leach 1974c, 1981a, 1985b, 1986f, 1992a).

Larry presented convincing arguments that

E. candela­

brum

is the correct name for an arborescent species in

Angola (letters to the editor of

The Euphorbia Journal

1987). He also fought against the apparently misapplied

lectotypification of

Stapelia variegata

(Leach 198 Id).

Convinced that the

International Code o f Botanical No­

menclature

could be improved, a number of proposals for

amendation of parts of the Code were unsuccessfully sub­

mitted.

Larry was a prolific collector, often in inaccessible lo­

calities in the

Flora zambesiaca

and

Flora o f southern

Africa

regions with ± 10 000 personal accessions being

taken up in various southern African and European her­

baria, although current collecting numbers are in the re­

gion of 18 000 through the inclusion of specimens sent

to him for study.

Larry discovered and described four genera and 150

species and infraspecific taxa in the Euphorbieae, Stape­

lieae and the genus

Aloe.

Yet his most valuable

bution probably was the tracking down of imperfectly

known species to their type localities and establishing

their correct identity. His wide interest in plants resulted

in his being commemorated in the following taxa:

Aloe

leachii

Reynolds,

Cheilanthes leachii

(Schelpe) Schelpe,

Crassula leachii

R.Fern.,

Dombeya leachii

Wild,

Echid-nopsis leachii

Lavranos,

and

In 1990 Leach was the first recipient in Africa of the

Golden Cactus Award of the International Organization

for Succulent Plant Study based in Zurich (Figure 3). He

was also honoured with the Harry Bolus Medal by the

Botanical Society of South Africa in 1968 (Schelpe 1969),

the Gold Medal of the Rhodesian Scientific Association

in 1977 (Kimberley 1977), the Certificate of Merit of the

South African Association o f Botanists in 1981 and the

Allen Dyer medal of the Succulent Society of Southern

Africa (Anon. 1994).

Larry was elected a Fellow of the Aloe and Succulent

Society o f Zimbabwe in 1975 and the Cactus and Succu­

lent Society of America in 1983 (Mitich 1983). He was

a vice president of the Rhodesian Aloe & Succulent So­

ciety and the African Succulent Plant Society of England.

Various tributes to Larry Leach appeared in Gomes e

Sousa (1971), Schelpe (1969), Kimberley (1988), Mitich

(1983) and Downs (1996).

South African botany has profited immensely from the

w ork of highly motivated, well-versed amateurs. Larry

Leach was one of the greatest among them.
